The next generation of Badger Bounce Back: determining COVID-19 activity level in our local communities
COVID-19 remains very contagious and most people in Wisconsin are still at risk of getting sick from the virus. To evolve Badger Bounce Back to give local communities the tools they need to respond to COVID-19, we are shifting to assessing the COVID-19 activity level in counties and Healthcare Emergency Readiness Coalition (HERC) regions.
What are these data?
Regions and counties are classified as high, medium, or low activity levels for disease spread by combining the case burden and trajectory indicators (see definitions for case indicators below the map and table). This is one metric that will be further contextualized as DHS adds more local metrics to this site.
Your local and tribal health departments can use these data, in conjunction with other local data and context, to help understand the COVID-19 activity in a county or HERC region of the state. While this information can help inform individual residents and local leaders of business and other institutions as they take steps and precautions to reduce the spread of COVID-19, we strongly encourage members of the public to visit their local or tribal health department website for additional information and recommendations for local action.
Why is DHS sharing these data now?
At the request of our local public health partners, and in recognition of the fact that local decisions now drive our response efforts we are adding tools to our toolbox to fight COVID-19. This is the first in a series of data dashboards that DHS will provide to help communities and individuals assess their COVID-19 activity level and response. What we want you to remember is that the virus has not changed; when you physically distance, wear a cloth face covering, limit your trips, and wash your hands, you are practicing the best health measures to protect yourself against COVID-19.
We plan to update our data each Wednesday by 2 p.m.
Case indicators defined
Burden (case rate) and trajectory (case change) indicators are based on confirmed COVID-19 cases. The COVID-19 activity level maps burden and trajectory indicators based on whether the burden status is low, moderate, moderately high, or high and whether trajectory status is significantly shrinking, growing, or have no statistically significant change.
Burden (case rate)
Burden is the total number of cases per 100,000 Wisconsin residents in the last two weeks.
|Burden Status||Value (per 100,000 Wisconsin residents in the past two weeks)|
|Low||Case rate is less than or equal to 10.|
|Moderate||Case rate is greater than 10, but less than or equal to 50.|
|Moderately High||Case rate is greater than 50, but less than or equal to 100.|
|High||Case rate is greater than 100.|
Trajectory (percent case change)
Trajectory is the percent change from previous to current week and p-value (indicates statistical significance) from a test against the percent change equal to zero.
|Trajectory Status||Value (change from prior 7-day period to most recent 7-day period)|
|Shrinking||Percent change in cases is less than or equal to negative 10 percent, and p-value is less than 0.025.|
|Growing||Percent change in cases is greater than or equal to 10 percent, and p-value is less than 0.025.|
|No Significant Change||Any other conditions besides those that meet the "shrinking" or "growing" statuses described above.|
COVID-19 activity level
COVID-19 activity level is a summary indicator based on whether the burden (case rate) status is low, moderate, moderately high, or high and whether the trajectory (case change) status is significantly shrinking, growing, or have no statistically significant change*.
*As defined in the burden and trajectory status tables above.
|Low||No Significant Change||Low|
|Moderate||No Significant Change||Medium|
|Moderately High||No Significant Change||High|
|High||No Significant Change||High|
